2005 Chevrolet Silverado 1500
Programmed immediately. Hooked it up to a new Kenwood. I had to connect the blue/yellow remote wire to the brown wire and then insert to the plug into the female end with the brown wire. Nice to have my steering wheel controls back!
Pros: Programs immediately. Calling their customer support is excellent too
Cons: dodgey instructions but it's a breeze.
